Is it possible that GT Masters/TCR Germany run on some city circuit?
Like Norisring or something like AVUS?

Avus hasn't been a thing for a long time. And Norisring is only one weekend a year and that's for DTM. GT Masters was a support race there once, but they really didn't like the experience, having to run at weird times of the day and being shuffled to the back of the paddock.

I know AVUS isn't running in last 15 years, but some similar city circuit.
What about race on old airfield like Diepholz or Zeltweg?

Not going to happen... nothing even on the horizon. The airfields really were a stop gap solution for when there were only two servicable tracks in Germany (Hockenheim and Nürburgring) - but now there's also Lausitz, Oschersleben and Sachsenring. I'd love to see something different than those for a change but I really don't see it happening.

I meant Zeltweg that was run in F1 and Sportscar in 1960's.
That was held on some Air Force Airfield If I am not wrong.

You're quite right, my mistake. It was used in the 60s until they built the Österreichring nearby (so its successor, the Red Bull Ring, is also in the municipality of Zeltweg). Doesn't look like it was a very interesting track, though.

Interesting that those airfield tracks in Germany and Austria tended to be underwhelming, whereas the ones built on the perimeters of airfields in the UK, like Silverstone, Thruxton and Goodwood, are belters. But I digress.
